Resumo
LiFePO4/C/reduced graphene oxide (rGO) composites with different morphologies were synthesized, allowing evaluation of the electrochemical performance as a function of the sample morphology. LiFePO4 particles anchored on rGO sheets and rGO sheets wrapping LiFePO4 agglomerations were two of the most pronounced features observed. The structure with LiFePO4 particles anchored on rGO sheets was found to be the most optimal and give rise to both increased capacity and improved rate capability.
